ORA-00936: missing expression Solution
Did you get an ORA-00936: missing expression error? Learn what it means and how to resolve it in this article.
ORA-00936 Cause
ORA-00936 CauseThe error you’ve gotten is this:
Oracle’s official “cause and action” that appears along with the error is:
Cause: A required part of a clause or expression has been omitted. For example, a SELECT statement may have been entered without a list of columns or expressions or with an incomplete expression. This message is also issued in cases where a reserved word is misused, as in SELECT TABLE.
Action: Check the statement syntax and specify the missing component.
So, in summary, the query is missing some clause that it needs in order to run.
ORA-00936 Solution
To resolve the ORA-00936 error:
Missing Columns
The ORA-00936 error often occurs when you leave out the columns in the SELECT clause.
This is because you need to list the column names after the word SELECT and before the word FROM.
This query should work:
Missing FROM
This error can also occur if you don’t have a FROM keyword in your SELECT statement.
For example, this query will display an error:
There is no FROM clause in this query, so you’ll get an error.
Correct the query to add the FROM clause, so it knows which table to query.
Remove Commas
Sometimes you have all of the right keywords, but you’re still getting the ORA-00936: missing expression error.
For example this query gives an error:
The reason for this is because there is a comma after the final column “last_name”, and then there is the FROM keyword.
Commas should only be used when you want to specify another column or table, and not before a keyword like we have in this example.
To correct it, remove the comma.
ORA-00936 in UPDATE Statement
If you’re getting an ORA-00936: missing expression in an UPDATE statement, then the same steps can be taken:
ORA-00936 in INSERT Statement
Just like the UPDATE statement, you can also get an ORA-00936: missing expression in an INSERT statement.
The same steps can be taken:

How to resolve the ORA-00936 missing expression
Description
ORA-00936 : missing expression is one of the common error everybody working in Oracle SQL must have faced some time. This generally happens when you omit important thing in the Sql statement i.e you left out an important chunk of what you were trying to run 
Cause of ORA-00936 : missing expression
This Oracle error is mainly related to the SQL SELECT statements. One obvious reason is select column list is missing or expressions in the selected columns are incomplete.
Check list to run to resolve the ORA-00936 missing expression error
(1) It happens when you forget to list the column in the select statement
The correct way would be list the column you want to select
(2) We sometimes makes mistake in the usage of Distinct statement. Following statement will fail with ORA-00936
Having two distinct clause does not make sense and give error
distinct can be used in the starting only
So correct statement would be
** operators works in PLSQL but not in SQL, We need to use Power function for it, So correct way would be
Here you forget to mention column name after the concatenation operator, the correct SQL would be
(5) When you add extra commas in the list of column
So we need to double check the SQL statement when we hit this error and make sure we are doing the common mistake
(6) This error will also come if you omit the From in the SQL statement
Here we missed to mention the from clause.SELECT statement has three parts: to wit: “SELECT->FROM->WHERE
You can omit where clause but select and from are necessary
(7) It can also occurs in insert statement like below
We don’t need values as in this statement
(8) We can sometimes mix up user-defined functions and Oracle functions, and doing so can lead to confused syntax that would result in an error message.So avoid them
(9) There are Oracle some bugs also
(a) Bug:4567818 base Bug#:4192148 – unpublished on 9207
(b) Bug:4212516 (unpublished) on oracle 10.1.0.4.0.
With these bugs, ORA-00936 error is thrown when the SELECT ON view fails. Basically, ORA-00936 is thrown when a SQL view is created from “create or replace view MY_VIEW as select t.*,other_tab_col from tab t, other_tab”.This creates a view definition that is incorrect in the DBA_VIEWS, thus throwing ORA-00936 and possible core dumps.In order to fix the bugs and resolve ORA-00936, MetaLink offers these solutions for the appropriate version:
Fix for 9.2.0.7 :Patch 4192148 is available for Solaris (64bit) and AIX5L Based Systems (64-bit).Fix for 10.1.0.4 :
Patch 4212516 is available for most of the platforms.
In nutshell, ORA-00936 missing expression can be resolved by carefully checking your SQL statement.

ORA-00936 Error Message
Some Oracle mistakes are not nearly as intimidating to resolve as the error message would seem to indicate. The ORA-00936 is the perfect example of such a case. This error provides an excellent case where thinking too hard about the answer will cost you far more time and effort than needed.
The ORA-00936 message is a missing expression error in Oracle. All that ‘missing expression’ means is that When attempting to operate a query, a particular part of the clause necessary for it to function was omitted in the text. Stated simply, you left out an important chunk of what you were trying to run. This can happen fairly easily, but provided below are two examples that are the most common occurrence of this issue.
The first example is the product of missing information in a SELECT statement, which triggers the vast majority of ORA-00936 errors. This occurs when entering SELECT on the first line, but then failing to reference the list of columns following the SELECT. If you just enter ‘SELECT’ on line one, and then ‘FROM abc;’ on line two, the ORA-00936 message will be prompted. To fix this, go back and choose a column to input after SELECT so that line one looks something like ‘SELECT distributors_name, distributors_location’, with line two remaining the same. This will correct the error and allow the SELECT statement to process.
Conversely, the error can happen in the latter half of a SQL statement. If the FROM clause within the statement is omitted, the error message will be thrown. You will need to look back at the syntax of the statement and make sure that for items such as SELECT statements, the next line includes a FROM clause (such as ‘FROM list_of_suppliers’) so that the SELECT clause knows where to be triggering information from within the database.
The ORA-00936 error can be prevented by double-checking instances of SQL clauses and making sure that all statements are derived from the proper syntax. This, of course, extends beyond just SELECT statements but also FROM and WHERE statements as well (or any other clause meant to trigger a query). Be positive that any Oracle functions used are spelled out properly, and keep tabs of user-defined functions. It can be easy to mix up user-defined functions and Oracle functions, and doing so can lead to confused syntax that would result in an error message. The representatives at a licensed Oracle consultant firm can work with you to make sure that you understand the difference between these types of functions and have proper knowledge of the individual functions that come pre-equipped with Oracle database software.

3. если ты во FROM указываешь несколько таблиц, то должно быть минимум одно условие связи на каждую таблицу. Иначе получишь декартово произведение строк таблиц.
В данном случае я бы выборки по годам объединил по UNION
Да нет же, достаточно сделать trunc(var_date,’yy’)
AGK, не увольняются,таблицы вообще не изменяются
нужен год 1995-1998
с 2000 года
Это не реальная БД,а просто пример
Каким образом могут быть люди приняты в 1995 году, если учет ведется с 2000 года?
Значит число людей, принятых во все указанные годы равно 0?

Правильно введенный бредовый запрос ничего кроме бреда вернуть не может. Если вы будете и дальше так вольно обращаться с постановками, из Вас ничего путного не получится. Запрос сейчас нацарапаю.

Нельзя числа использовать в качестве алиасов. Надо их в кавычки брать. Я думаю, что Ваша ошибка, в основном, из-за этого была

Correct syntax below.
Although above query would work but the recommended way is by using ANSI SQL JOIN syntax is
As people have commented you missed the FROM statement in your select.
I would also suggest not just declaring all your tables in the FROM and specifying links in the WHERE clause, but instead join the tables together using LEFT JOIN and/or INNER JOIN s, etc.
Below is the query I think should cover what I have tried to explain above.
